common with the wooden-back brushes andas the bristles becoine deteriorated or worn down, any worn sets ,may :be quickly re moved and the brushj'refilled at. *smallex pense, thus economizingin the final cqstof the device.

The sets of bristles are so arranged the outer. circle 7 ,constitutesfla' thickly formed wall which perinits little,*if any, of

same is in" useinits' verticalworkingsposition, as shown-in Fig. 2. Thebristles forming the v 'inner oftheconcentric circles are not positioned as closely as the outer circle 7 off lJIlStlGS, thereby forming tortuous passageways 8 which slightlyretardthefree flow of theliquid from the centervof the brushdiametrically toward its outer edge;

The innermost circle of bristles 9 define a spraying space centrally oflthe brush in which space there are no bristlesthuspermitting a clear opening from'fthetoutside to the batkof thebasej-3 atithe center' thereof. .A spraying rose 10' is positioned on the back :within" this space. As thsolution would iattack any fastening means for securing this roseeinplace it" is formedlintegrally with the, base.-- In the device disclosed the-rose is formed .ofa thin disk of celluloid mounted .in'position by dissolving the face ofthering by the use of a. solventsuchlas alcohol) and .thenpressing the rose-forming disk'into position onthesoftened ring, so that when resolidified the rose forms an integral portion of the base. Anotherway to form therose illustrated is to bore the back to within ones'ixteenth of an inch, thus leaving a plate ,10

plate so formed; p I I i 7 Prior to mounting therose in place,.the

7 "back of the baseis drilled to prOVideLa recess l'2','and.counter drilled toprov'ide an opening 13, into which is threaded the end space 12. Theportion of therpipe fitted in -pipe'isisecurely bracedin plate so -tha't'it may be used as a handle for manipulating the brush; The flow; of liquid to the'brush iscontrolled by means of a valve 15 of'any die 16: disposed relativelylclose to the'back of-the brush so that the'supply of-liquidis immediately available at the brush as soon the valve 159is openedandso' that when the valve :is: shut oflpthe minimumam'ount 'of liquid will be contained in the brush. I

In the forrnof the'rpiping attachment 1 show-ngin Fig.1? aY 17 is substituted for the l pipe 14 and a longhollow handle 1 8iis K-threaded onto the' arin 1'9 ofthe This ejected fine sprays.- i 3 'While I havejshown. and described," and have pointed out in the annexed claims,-ce'rintegral Withthe backhand perforate the claim? a .7 of a pipe 14 for conducting the liquid to the l closed byl mean f; a l 21 By" means of a device of this'character, it

isflpossible to manipulate the handle 16 so 1 that the requisite amount of liquidwill be sprayedffromhthe rose, just sufficient to the liquid passing-off the brush when the" cover the surface uniformly, without any the liquid is diffused laterally and; is. passed 7 V from one set of bristles toanother across the facet-of the brush all t'ending to"distribute the liquid overthe entire face ofthe brush.

While the vliquidis thus permitted to travel diametrically across the face. of the brush,

th'egouter thicklybristled circle f bristles will act to retard the dischargecof' theliquid olfthe side edge of the brush.

In practice it is usualto disconiiect this brush from its supply of cleansing material 1 ancllconnect it to a water supply. During this use with'water the brush may be used as a scrubbing brush orit'mayjbe with drawn from contact ,=With the surface being sprayingdevice with the rose acting to discleaned andthe devicev used simply as a 1 11' pro ecting from the base 3,(preferably tribute the cleansingwaterin forcefully tain novel features of in invention, itwill beunderstood that various omissions, substitutions and changes in the formand details of the device illustrated andin itsoperationmay be made by those skilled inFthe I art'without departingfrom the spiritiof the invention; Y
